PARC 273 Galvanostat GPIB Commands

[Michael_Munroe]

I need to read the measurement results from a PARC 273 Galvanostat/Potentiostat. Unfortunately, I do not have any documentation on the unit. Does anyone have a copy of the GPIB command set handbook which contains the protocol required to read the data from the unit? Can you please provide me with the commands and data format to transfer the result data to the PC?

Hello,

This is a way too late reply, but I have the same problem.

Please look at the following program as entered into the Headstart software. It causes the potentiostat to scan from -1 V to +1 V and then back to -1 V, collecting a total of 101 data points for each 100 milliseconds:

DCL

LP 100

SCV 2

MM 2

INITIAL 0 0

VERTEX 50 8000

VERTEX 100 0

BIAS -1000

INTRP 0

ASM

NC

CELL 1

TC; WCD; CELL 0

It was noted in the Headstart book that the last command in the sequence instructs the instrument to take the curve, wait until the curve is completed, and then turn the cell off.
